Problem is the output tube from the pup was not connected to the upper half of the drive

Ok, so if they became separated wouldn't water still be drawn in by the pump and just leak out the front of the drive housing? The impeller didn't seem to be drawing any water in at all.

Did you pull the impeller? See how hard the set is on the vanes.

 

[Nick36]

Do you mean how flexible they are? They seem pretty flexible and there are no cracks in the rubber or anything. To me (untrained eye) it seems to be in good shape

Don't know how much sand was on top the lower half, but it appears sand and water made it thru the pump.

On another thought, what does the engine coupler look like?

Also rotate the drive shaft and verify it does rotate the lower

The face seal was totally gone too. Bought the kit and installed new impeller, housing, gaskets, face seal, o-rings and oil seal carrier. Going away for the weekend, but I'll report back as soon as I can! Thanks for the help.

 

[Nick36]

Oh, and the engine coupler looks good and the drive shaft does rotate the prop when I've got it engaged in fwd gear

Impeller kit fixed the issue. Happy to have moved on from that. Thanks for the help
